Azerbaijan Airlines Flight 56 was a scheduled domestic passenger flight from Nakhchivan to Baku operated by Azerbaijan Airlines which crashed on 5 December 1995, killing 52 people. The aircraft servicing the flight, a Tupolev Tu-134B-3, experienced engine failure while climbing. The pilots performed a forced landing that required a sharp right turn to avoid an apartment block. The aircraft crashed in the south-western outskirts of Nakhchivan, 3,850 m (2.39 mi) from the airport runway. The crash became Azerbaijan Airlines' deadliest accident. The airline no longer operates the Tu-134.
